6. Operating Instructions
6.1 Charging Batteries
Once batteries are inserted and power is connected, the charging hub will automatically begin charging. It features a Smart Priority system:
- The hub will identify the battery with the highest power level and charge it first.
- Once the first battery is fully charged, it will proceed to charge the next battery with the highest power level, and so on, until all batteries are fully charged.
Approximate Charging Times:
- For HS360E batteries: Approximately 70 minutes per battery.
- For HS360D batteries: Approximately 90 minutes per battery.
Figure 4: Smart Priority Charging. This graphic illustrates the charging hub's ability to charge three batteries sequentially, prioritizing the battery with the highest current charge level first. It also highlights the 36W fast charging capability and the typical charging time of 70-90 minutes for the first battery.
6.2 Auto-Discharge Function
To maintain optimal battery health and extend lifespan, the charging hub features an Auto-Discharge function:
- If fully charged batteries are left unused in the hub for more than 3 days, the charger will autonomously begin to lower the battery level.
- Over approximately one week, the battery level will be reduced to 70%-75%, which is the ideal storage charge for lithium-polymer batteries.
Figure 5: Auto-Discharge for Battery Health. This image visually explains the auto-discharge process, showing a battery at 100% on Day 1 and Day 3, then automatically discharging to 75% by Day 11 to optimize long-term battery health.
6.3 Using as a Power Bank
The charging hub can also function as a power bank:
- Ensure at least one charged drone battery is inserted into the hub.
- Connect your external device (e.g., smartphone, tablet) to the USB-C IN/OUT port on the charging hub using a compatible USB-C cable.
- The hub will begin to supply power to your device, drawing from the inserted drone batteries. It will prioritize discharging the battery with the lowest current charge level first.

6.4 Checking Battery Level
To check the charge level of the inserted batteries:
- Briefly press the power button on the side of the charging hub.
- The LED indicators on the front will illuminate to show the current charge status of the batteries.
7. Maintenance
- Clean the charging hub with a soft, dry cloth. Do not use liquid cleaners.
- Store the charging hub in a cool, dry place when not in use.
- If storing batteries for extended periods, ensure they are at the recommended 70-75% charge level (the auto-discharge function assists with this).

8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Batteries not charging. | No power supply; batteries not inserted correctly; damaged cable/adapter. | Ensure power adapter is connected and working. Re-insert batteries firmly. Try a different USB-C cable or power adapter. |
| LED indicators not lighting up. | No power; power button not pressed. | Connect power. Briefly press the power button to activate the display. |
| External device not charging (Power Bank function). | Drone batteries are low; device cable incompatible; device not connected properly. | Ensure drone batteries have sufficient charge. Use a compatible USB-C cable. Reconnect the external device. |
| Auto-discharge not occurring. | Batteries recently charged; less than 3 days elapsed. | The auto-discharge function activates after 3 days of inactivity for fully charged batteries. Allow sufficient time. |
